PURPOSE:To provide a carbon-metal composite material, excellent in bending strength and abrasion resistance and suitable as sliding plates for pantographs. CONSTITUTION:A raw material for a carbon material composed of a carbon aggregate; a binder pitch, etc., is mixed with dendritic electrolytic copper powder at 10-40vol.% blending ratio. The resultant mixture is then hot press formed at 500-600 deg.C temperature and burned. |
